SANITARY NURSERY-CHAIR.

' To all whom it may concern:

Be it known that I, DAVID R. COLLIER, a

of Gardner, in the county of Vorcester and State of Massachusetts, haveinvented certain new and useful Improvements in Sanitary Nursery-Chairs,of which the fol lowing is a specification.

The OlOJBQt of the present lnvention is to provide a sanitary nurserychair which 18 capable of being folded so that it may be easily carriedor stored in a small space.

Of the accompanying drawings which illustrate one form in which theinvention may be embodied: Figure 1 represents a side elevation of thechair in open position ready for use. Fig. 2 represents a rearelevationof the same. Fig. 3 represents a horizontal section in the planesindicated by line 3-3 of Figs. 1 and 2. Fig. 4 represents a vertical.section, on a larger scale,

looking toward the rear from the plane indicated by line 1-4:- ofFig. 1. Fig. 5 represents a side elevation of the structure included inFig. 1. Fig. 6 represents a perspective view of the structure shown byFig. 5, omitting the portion of the seat which is included in Fig. 5.Fig. 7 represents a perspective view of those portions of the stationaryframe structure which are included in Figs. 5 and 6. Fig. 8 represents aperspective view of the movable elements included in Fig. 8, the samebeing shown in the position corresponding to closed or folded conditionof the chair. Fig. 9 represents a side elevation of the chair in foldedcondition. Fig. 10 represents a rear elevation of the chair in foldedcondition.

The same reference characters indicate the same parts wherever theyoccur.

The main seat of the chairis indicated at 12; The seat is afiiXed to asubstantially rectangular frame which comprises side bars 13, 13, afrontbar 14, and a rear bar 15. (See Fig. 2.) The ends of the rear bar areconnectedto the rear ends of the side bars by corner pieces 16; One ofthese corner piecesis shown in detail by Fig. 7.

The legs of the chair are indicated at 17. For the purpose of attachingthe legs to the seat frame just-described, the forward ends of the sidebars 13 are bent downwardly; as indicated at 18, and the corner pieces16 are providedwith depending por- Specification of Letters Patent.

tions 19. The front legs 17 are connected to the portions 18 by pivotstuds 20, and the rear legs 17 are connected to the POT. tions 19 bypivot studs 21. The axes of these pivot studs are substantially inalinement with each other. The lower ends of the legs are curved, asindicated at 17 for the purpose of giving a neat appearance and for theadditional purpose of extending the base from front to rear. Each frontleg is connected with the corresponding rear leg bya connecting portion22. Forconvenience in manufacture, the two legs and connecting portionon each side are made from a continuous strip or bar. The pivotalconnections between the legs and the seat frame enable the legs to swingunder the seat to the position shown best by Fig. 10. The rear legs areprovided with stop pins 23 which are adapted to abut against the lowerends 19 of the corner pieces when the legs are opened for use, for thepurpose of limiting the opening movement of the legs. Figs. 2 and 4 showthese stop pins engaging the portions 19*.

1 A back-rest or support isindicated at 24;. This back-rest is carriedby a swinging frame 25 which is connected to the corner pieces 16 by thepivot studs 26. The swinging frame is adapted to swing forwardly anddownwardly from the position shown by Fig. 1 to the position shown byFig. 9, so that the back will lie closefto the seat. The swinging frame25 is shown as being made of a strip or rod which is bent to the formresembling an inverted letter U, the horizontal connecting portionindicated at 25 (see Fig. 2) affording a convenient handle whereby theframe may be grasped to open or close the same and whereby the chair maybe carried. The ends of the rod are fixed to plates27 which constituteplates 27 are provided with cam slots 28 whose function is to open andclose the legs when the back is opened or closed. These cam slots areoccupied by studs 29 (see Fig. 8) which have heads 30 at their outerends. The cam studs are connected with the rear legs by links 31.Connecting pieces 17 are afliXed to the rear legs by means ofthe pivotstuds 21 and stop pins 23 to afford convenient means for providing thedesired connection wit-h the links 31.

The cam plates 27 are adapted to move the studs 29 vertically and thusswing the legs in the manner hereinbefore explained. The movements ofthe stud 29 are guided by the corner pieces 16 which are provided withvertical slots 32 through which the studs extend. The ends 28 of the camslots which are farthest from the pivots 26 are substantially concentricwith relation to the pivots. hen the back and legs are folded as shownby Figs. 8 and 9, the cam studs 29 occupy the portions 28 and the legsare thereby locked in folded position so that their weight will not haveany tendency to open the chair.

Swinging arm rests are indicated at 33. These arm rests are preferablymade of strips of flat metal whose ends are bent downwardly as indicatedat 34. The lower extremities of the portions 34 are mounted upon pivotstuds 35. The pivot studs at the front are carried by pieces 36 whichare affixed to the rectangular seat frame. The pivot studs 35 at therear are mounted in the corner pieces 16, as shown by Figs. 2, 4

- and 6. hen the arm rests are open for use they are locked to the backframe by latches 37. These latches are connected to the sides of theback frame by pivot studs 38, and they are provided with projections 39which are adapted to enter suitable openings formed in locking pieces 40aflixed to the arm rests. Springs 41 anchored to the back frame andconnected to the latches normally hold the latter in locking position.When it is desired to fold the chair, the arm rests are folded inwardlybefore the back and legs are folded. Fig. 10 shows the arm restsextending toward each other and overlapping each other in foldedposition directly over the seat.

Side guards are indicated at 42. The lower edges of these guards arepivotally connected to the seat, and the upper edges are connected tothe arm rests so that the guards will open and close with the arm rests.For the purpose of connecting the guards with the seat, the lower edgesof the guards are provided with strips 43 whose ends are turned inwardlyas shown by Figs. 2 and 9. These ends are mounted upon pivot studs 44which are supported by brackets 45 affixed to the seat. The axes of thepivots 44 are substantially in alinement with the axes of the pivots 35which connect the arm rest with the seat frame. The arm rests areprovided with slots 46 (see Fig. 9) for the reception of a strap orguard 47 which may extend across from one armrest to the other toprevent the occupant of the chair from falling forward.

then the chair is open for use there is sufficient space beneath theseat and between the legs for the reception of a vessel such as thatindicated at 48 in Fig. 2. The seat 12 is provided with an opening 49the outline of which is represented by dotted lines in Fig. 2. Acollapsible screen for concealing the vessel is anchored to the bottomof the seat 12 and to the connecting pieces 22 which connect the legs.This screen is shown as comprising side pieces 50, 50, of suitableflexible sheet material, and a front piece 51 of similar material. Theupper edges of the front and side pieces may be secured to the bottom ofthe seat by any suitable means, such as tacks. Fasteners indicated at 53serve to connect the lower edges of the side pieces to the connectingpieces 22. The vertical meeting edges of the front and side pieces arejoined, as by stitches or any other desired means. A rear flap orscreen, indicated by dotted lines 54 in Fig. 1, may be used to concealthe vessel from the rear, but this flap may be omitted if desired. Thevertical meeting edges of the front and side flaps 50 and; 51 arepreferably joined, as by stitches or otherwise; and if the rear flap 54is used, the same may be likewise oined with the side flaps.

An auxiliary seat is indicated at 55. This seat may lie upon the seat 12when desired and is adapted to cover the same so that the opening 49will not be apparent. As shown by Fig. 2, the rear edge of the auxiliaryseat is connected by hinges 56 to the seat 12. lVhen it is desired touncover the seat 12 the auxiliary seat may be swung upwardly about itshinges so that it will rest against the back 24.
